Duty and Freight Add 16.5% to Internal Combustion Engines From Japan

Japan shipped $3.7 billion of internal combustion engines to U.S. buyers in 2025. USITC reported an effective calculated-duty rate of 13.7%, while measured freight added 2.8% of customs value — an additive 16.5% burden before domestic logistics. The JPY moved 0.1% in favor of the buyer over the last two weeks of the FX window. No country-specific unit value is available for this lane, so it is not ranked by landed unit cost.

• reported duty rate: 13.7%
• freight share: 2.8%
• total uplift: 16.5%

The alternatives, same arithmetic: Canada at 3.0% uplift, Mexico at 9.7% uplift, South Korea at 13.0% uplift. At least one listed lane has a lower duty-and-freight burden; total-cost ranking still requires comparable country-specific unit values.

The effective calculated-duty rate is USITC's reported calculated duty divided by the customs value covered by those duty observations for 2025; it is not a verified cash-payment amount or proof of any particular exclusion, quota, or trade-program claim. Freight is the lane's reported import-charges share of customs value. Reference data, not a customs quote.
